Network Access Protection (NAP) was a technology that allowed system administrators to create, enforce, and remediate health policies for client computers. Non-compliant client computers were restricted from network access until they met the health policy requirements. However, NAP was limited to Windows versions prior to Windows 10 and Windows Server 2016. NAP was deprecated in Windows Server 2012 R2 and is no longer supported in Windows Server 2016. It lacked compatibility with Windows 10 and Windows 11.
Unlike NAP, Intune is not tied to on-premises infrastructure. Intune is a 100% cloud-based unified endpoint management platform and it allows organization to manage and secure devices remotely, including windows endpoints from anywhere :-)
Moreover, Intune also has some key features such as Azure AD integration, Automatic enrollment and configuration and security policies. Intune does provide benefits such as users can work from anywhere with an internet connection, easy device reset and restoration, simplified deployment etc.
Intune is a powerful solution, but it requires an internet connection for management. It’s suitable for both organization-owned and BYOD (Bring Your Own Device) scenarios. So, in your case Microsoft Intune is a may work as a replacement for NAP as it provides cloud-native management for Windows endpoints, allowing organizations to manage devices securely from anywhere.
